Ceiling earthquake-resistant repair fittings

Abstract

To provide a ceiling earthquake-proofing repair fitting that ensures ease of level adjustment and fitting installation when fastening a frame reinforcement material and a ceiling underlayment material of an existing building. [Solution] When the semi-structural method is selected for the ceiling seismic retrofitting construction method, the strength of the metal fittings used to fasten the main structure and the ceiling substrate of the renovated area meets the characteristic value of 0.1 or less set by the Japan Structural Engineers Association. The fastening parts are joined with screws to allow for a variable adjustment range to accommodate unevenness in the ceiling reinforcement, and the top of the ceiling seismic retrofitting construction fittings is U-shaped to make it easier to join to the square pipe reinforcement. The ceiling level can be easily adjusted to suit the conditions of each site, while ensuring the required strength and being easily attached to existing reinforcement.

[0003] [Patent Document 1] Patent open 2021-085308 [Patent Document 2] Patent open 2017-040036 Summary of the Invention [Problem to be solved by the invention]

[0004] Ensure the required strength (eigenvalue of 0.1 or less) and ensure ease of level adjustment and metal fitting installation when fastening the structure and ceiling underlayment. [Means for solving the problem]

[0005] By combining angles and square pipes, strength is ensured and the construction is easy when fastening the structural reinforcement material and ceiling base material, and the ceiling level can be easily adjusted. [Effects of the Invention]

[0006] The tight connection of each component at the renovation site ensures strength while facilitating level adjustments and metal fitting installation. [Brief explanation of the drawings]

[0007] [Figure 1] This is a drawing showing the implementation of the ceiling earthquake-resistant renovation fittings of this invention. [Figure 2]This is a front view of the ceiling earthquake-resistant renovation construction fittings. DETAILED DESCRIPTION OF THE INVENTION

[0008] This semi-structural ceiling earthquake resistance renovation method aims to integrate the building with the structure, and secures the necessary strength by fastening the building reinforcement material to the ceiling base material, making it easy to adjust the level of the ceiling base material and attach metal fittings. [Example]

[0009] The following describes the embodiment with reference to the attached drawings. 1 is a reinforcement material for supporting the ceiling substrate from the existing building, 2 is the part connecting the ceiling earthquake-resistant renovation construction metal fittings and the reinforcement material, 3 is an angle and square pipe for ensuring strength, and 4 is a square pipe that serves as a joist support for hanging the ceiling substrate material.

Claims

1. When the semi-structural method is selected among the earthquake-resistant ceiling renovation methods, a combination of angles and square pipes is used to ensure the required strength (eigenvalue of 0.1 or less) of the metal fittings that fasten the main structure and the ceiling subfloor material of the renovated area.

2. The metal fittings are designed to accommodate length changes and each part is fastened with screws to ensure a wide range of adjustment.

3. The upper part of the metal fittings is U-shaped to make it easier to join to the square pipe reinforcing material.
